在Vue中,可以使用v-bind指令来动态绑定class。具体的语法是v-bind:class="{类名1:条件1,类名2:条件2}"。其中,类名1和类名2是要绑定的类名,条件1和条件2是布尔值,当条件为true时,对应的类名会被添加到元素上。例如,可以使用以下代码来动态绑定class:
```html
<div id="app">
<h2 v-bind:class="{active: isActive, line: isLine}">{{message}}</h2>
</div>
```
在上述代码中,isActive和isLine是布尔值,当它们为true时,对应的类名active和line会被添加到h2元素上。
